Detection and Chemical Profiling of Ling-Gui-Zhu-Gan Decoction by Ultra Performance Liquid Chromatography-Hybrid Linear Ion Trap-Orbitrap Mass Spectrometry

Ling-Gui-Zhu-Gan decoction (LGZGD), a well-known traditional Chinese medicine (TCM) formula, has been extensively used for the treatment of cardiovascular disease in clinic. However, the chemical constituents in LGZGD had not been investigated so far. In this study, an ultra performance liquid chromatography-hybrid electrospray ionization linear ion trap-Orbitrap mass spectrometry (UPLC-LTQ-Oribitrap-MS/MS) method was established for rapid...
